summary

My grandfather is a vitiligo patient, many years of vitiligo, has been good and bad, relying on drugs to maintain, this period of time the disease has become more serious than before, today I'll talk about the symptoms of vitiligo.

Symptoms of vitiligo

First, vitiligo can be found in all nationalities in the world. The incidence rate varies from region to region, and the color of the race is different. The more skin color is, the more the disease is occurring. For example, the number of patients in the United States is less than 1%, and India is as high as 4%. The prevalence rate of vitiligo is 0.1% to 2% in China. There was no significant difference in gender. All age groups were susceptible to the disease, but most of them were teenagers. About half of the patients were under 20 years old. The skin lesions are local depigmentation spots, often milky white, or light pink, with smooth surface and no rash.

Secondly, after vitiligo, the boundary of leukoplakia is clear, the edge pigment is increased compared with normal skin, and the hair in leukoplakia is normal or white. Most of the lesions occurred in the sun and friction injury parts, such as the face, upper legs, neck, forearm extension side and hand back, waist, abdomen and sacrococcygeal, axillary and pudendal, elbow and knee joints, etc. Leukoplakia is also often arranged in strips according to the distribution of ganglion segments (or skin segments), which is unilateral. In addition to skin damage, labia, labia, glans and inner prepuce mucosa are often involved. Leukoplakia may spread throughout the body, but the melanocytes in the retina, choroid and pia mater are not involved. In winter, there is depigmentation in the center or edge of the white spot. About 20% of the patients with leukoplakia are highly sensitive to ultraviolet light, and the development of leukoplakia is rapid after the sun exposure.

Finally, vitiligo will be due to mechanical stimulation, such as acupuncture, scratching, pressure on the skin (tights, hernia support, etc.) and other local stimulation, such as burn, infection, sunburn, frostbite, radiation, etc., which can make the patient's normal skin white spots, or make the original white spots expand, or even make the whole body's isomorphic reaction. The number of leukoplakia is variable, and it can rarely change or disappear by itself. However, in most cases, the number of leukoplakia gradually increases and expands, and the adjacent leukoplakia fuse into irregular large pieces, or even spread all over the body.

matters needing attention

Usually eat more foods containing tyrosine and minerals, meat (beef, rabbit, pig lean meat), animal liver, eggs (eggs, duck eggs, quail eggs), milk (milk, yogurt), vegetables (fresh vegetables, as well as radish, eggplant, winter bamboo shoots, fungus, kelp, etc.) beans (yellow beans, peas, mung beans, bean products), peanuts, black sesame, walnuts, raisins, snails, clams, etc Shellfish. Meanwhile, avoid chili, wine, beer or Baijiu, and tomatoes, because tomatoes contain lots of vitamin C. Vitamin C can interrupt the synthesis of melanin and prevent the regeneration of melanin. Other foods containing more vitamin C, such as orange, grapefruit, apricot, hawthorn, cherry, kiwi, strawberry, Bayberry and so on, should be eaten less or not.
